PCI_SYNC_IN in 1:1 mode, but is twice the frequency in 2:1 mode (processor/memory bus clock rising edges occur on every
rising and falling edge of PCI_SYNC_IN). See

has a programmable output hold delay for PCI signals (the PCI_SYNC_IN to output valid timing is also affected). The initial
value of the output hold delay is determined by the values on the MCP and CKE reset configuration signals; the values on
these two signals are inverted and subsequently stored as the initial settings of PCI_HOLD_DEL = PMCR2[5, 4] (power
management configuration register 2 <0x72>), respectively. Because MCP and CKE have internal pull-up resistors, the
default value of PCI_HOLD_DEL after reset is 0b00. Additional output hold delay values are available by programming the
PCI_HOLD_DEL value of the PMCR2 configuration register. See
